Electromagnetic valve

Abstract

An electromagnetic valve includes a plunger driven by an electromagnetic mechanism, a tubular spool moved by the plunger in the axial direction, a valve body having fluid passages, a sleeve accommodating the spool therein so as to be able to slide in the axial direction and fitted into the valve body, a ball member pressed into one end of the spool and a pushing member fixed to the plunger and contacted with the ball member.

What is claimed is:  
     
         1 . A an electromagnetic valve comprising: 
 a plunger driven by an electromagnetic mechanism,    cylindrical spool moved by the plunger in the axial direction,    a valve body having fluid passages,    a sleeve accommodating the spool therein so as to be able to slide in the axial direction and fitted into the valve body,    a ball member pressed into one end of the spool and    a pushing member fixed to the plunger and contacted with the ball member.    
     
     
         2 . An electromagnetic valve as set force in  claim 1 , wherein the spool has a penetrating passage penetrating in the axial direction and the ball member is pressed into an opening of one end of the penetrating passage.  
     
     
         3 . An electromagnetic valve as set force in  claim 2 , wherein the inner diameter of penetrating passage is the same as the inner diameter of the opening or is smaller than the inner diameter of the opening.
